Hey everyone,
I don't know if I am posting to the correct forum so please move this if there is a better forum for this.
I am having issues through SQL Server that I believe may be related to the SQL Server 2000 User Mode Scheduler.
First of all, I am running a single instance of SQL Server 2000 on a Quad Processor system. I was not around when the system was installed so I do not know how it was originally configured.
I am getting a reoccurring error whenever I try to do anything with replication or scheduled jobs.
Error 14258: cannot perform this operation while SQL server agent is starting. Try again later.
I found the following article regarding the above error:
http://support.microsoft.com/default.aspx scid=kb;en-us;303287
My question is, how to I determine if SQL is running in Fiber Mode or Thread Mode And if it is running in Fiber Mode, would I see any major performance issues by switching it back to Thread Mode And is any of this an issue in SQL 2005
Any suggestions or comments are welcome. Please keep in mind that I have absolutely no clue about this these user modes or threads/fibers or any of the SQL architecture stuff so please keep in simple.
Thanks,
Lee.

It would be a rare case that you would require fiber mode processing on a server, and it should only be done if you are certain via testing that it improves performance and/or are recommended to do so by an MS employee.
To check if you are running in fiber mode, run the following in query analyzer:
exec sp_configure 'show advanced options',1
go
reconfigure
go
exec sp_configure 'lightweight pooling'
go
If the value for the 'run_value' column is 1, then you are running in fiber mode and you should change it ASAP...to do so you'll have to run the following and then restart your SQL Service:
exec sp_configure 'show advanced options',1
go
reconfigure
go
exec sp_configure 'lightweight pooling',1
go
reconfigure
go
